means being composed of plural parts which open slightly and permit the wire to pass therebetween, then close onto and firmly grip the wire, and then, as a unit, move across the face of the cut-off die and sever the gripped portion of the wire with an absolutely square cut-off face, and then carry and transfer the cut-off portion, now a workpiece, to a push-out station; and to so arrange this cut-off mechanism with respect to other parts that it will return for a succeeding cut-off operation during the transfer of the workpiece to the fabricating die.

Referring to the drawings, I0 indicates the frame of a header, upsetting machine or the like, having a die block l l, in which is a fabricatin die I2 or the like. This die lock may be held rigid in the frame by any one of many convenient means well known in the art. Slidably held in the face of the die block H, by a gib l5 or the like, are the two cutter slides l3 and l4, the former having a lug IT at its outer end and the latter a similar lug l8 at its outer end, which are in line with each other. Between these lugs; and passing through an opening in the gib I5, is a rod l9, one end of which bears against the lug l1, and the other end of which passes through the lug l8, with a nut 20 threaded on the outer end thereof. When the die block II is to be removed from the header, the nut 20 on the rod I9 is tightened. This compresses the spring 23 and relatively the tension against the lugs l1 and It on the slides l3 and I4, so that they may later be brought together free from contact with the V roll59 and the adjusting screw 52. .As so positioned, the entire die block unit may be removed the lug I1 and limits movement of the slide I3 in one direction. Both slides are reciprocated by positively actuated mechanism. Such mechanism for moving the slides to the left, when viewed in their relative positions, as shown in Figure 1, comprises in part a rock arm 25, carrying a cam roll 59, fixed on a rock shaft 26, journaled in the frame I0, a rock arm 21, also upon the shaft, to which the connection 28 is hinged, by a pin 29 or the like. J ournaled on the pin 30, fixed in the frame ID or other rigid part, i a rock arm 3|, to which the yoke 32 and cam roll 33 are journaled. The cam roll rides against the face of a cam 34 fixed upon the side shaft 35. Between the yokes 28 and 32 is a connection rod 35, threaded in the yoke 28 and passing through an'opening in the yoke 32, with lock nuts 31 on its inner end.

Between the collar 38 on the connection rod 35 and the yoke 32, is a spring 39. Fixed to the frame I is a bracket 40, within which aplunger M is movably mounted and partly surrounded by a spring 42, between the screw 43 andga shoulder on the plunger. One end of this plunger. engages a shoulder (Fig. 2) on the rock arm SI and exerts a tension thereon that holds the'cam roll 33 against the face of cam 34-. The connection rod 36 and associated parts provide means for adjustment of, the position of the rock .arm 25, by which the slides I3 and I4 are moved in one direction (toward the left in Figure 1). ,These slidesare moved in the opposite direction (to the right when Viewed in Figure 1) from a cam 44 on the side shaft 35, through a rock lever 45 fulcrumed on the pin 30. 45 is a cam roll 46, whichrrides against the face of the cam 44 and is held thereagainst, by a spring pin' 48 pivotally connected to the rock lever 45 and slidable through a nut 49; threaded in the frame In (Fig. 1) being surrounded by a spring 47.

Movably mounted in the frame I0 is a plunger 59 connected by a link I with the rock lever 45, and whereby areciprocating motion is imparted thereto from. the cam 44. An adjusting screw 52 is threaded in the inner end of the cut-off plunger 5|.and;held in its adjusted positions by a nut 53.) The outer end of this screw 52 abuts against the lug I8. Secured to the inner adjacent end of each of L the slides I3 and I4, by'screws or other convvenientmeans, is a cutter I6. Inthe inner end of: each of these cutters is a recess BI that is substantially the same shape in cross section as a portion of the workpiece. When the cam roll 46 is on the low portion of the cam 44, the slides I3. and I4 with the cutters I Bnthereon, are in a position wherein the. opening 51 between the innerends of the cutters and formed bythe recesses SI of the same shape in cross section as the workpiece, is opposite and in register .with the wire line, that is, the line of feed of'the'wire through the cut-off die 55. When the cam roll 46 is on the high portion of the .cam 44, the

slides I3 and I4 and. the cutters I6 thereon, are

in their right hand position (Fig. 1),'the. opening 51 then being in register with the push-out line 58. A push-out pin 54 at this station operates in a well known manner. Thecamtiming is'such that when the plunger 50 ismoving the-slides and cuttersfrom the wire line to the push-out line, the cam roll 59 will maintain its contact with'the lug I1. 'When the cutters are moved in the reverse direction? thessource of Upon. the rock lever like.

25 and the cut-off plunger moves rcarwardly without losing contact with the lug I8.

When the slides are in the position wherein the opening 5? is in register with the wire line, and also when in register with the push-out line, the cutters I6 are moved and held apart a limited distance by the spring 23, thus allowing a free passage of the wire and workpiece therebetween.

The screw 52 in the plunger 55 is adjusted so that the cutter I6 connected with the slide I4 stops just short of the push-out line.

During this action the rock arm 25 continues its movement for a slight over-travel, until thelug I! on slide I3 engages the stop screw 24 and the cutter I5 thereon stops just beyond the push-out line. The spring 23 now holds these cutters slightly separated, pushing the slide I3 away from. the slide I4, as determined by the stop pin 24, releasing their grip on the workpiece held therebetween.

The push-outpin 54, operating in a well known manner, projects the workpiece from between the cutters into the fingers of the transfermechanism. The slides'l3 and I4 are returned so that the opening 57 again-registers with'the wire line, through the action of the cam 34, arm; 25 and associated parts. During the first portion of this return movement the slide I3 is actuated independently until the cutter thereon engages the cutter on the'slide I4. Both slides and cutters now move as a unit until the opening 51 is approximately in register with the wire line. This is due to the fact that the rock arm 25 discontinues its pressure upon the slide I3, but the cut-off plunger 5|] continues its movement for aslight over-travel. The spring 23 now separates, the slides I4 and slide I3 and the cutters thereon a. limited distance sufficient to permit the wire to pass freely therebetween untilthe end thereof engages a feed stop or the A portion of one form of-feed stop 55 is shown in Figure 6, but anypreferred form may be used within this invention. Immediately the power is applied thereto through therockiarm end portion of the wire is-between the cutters, the plunger 59 advances the slide I4 and the cutter attached=thereto up to and in contact with the projecting portion of the wire. At the same time the cam 34 rocks the arm 25, advancing the slide I3. and its cutter until the latter contacts with the projecting portion of the wire. When so positioned,-the two cutters firmly and rigidly grip that portion of the wire projecting beyond the face of thecut-oif die 55. The slides now move the cutters and theworkpiece held firmly therebetween from the wire line to the push-out line and during such movement the cutters sever the projectingportion of the wire from the wire length. The spring 39 compensates for any inaccuracy in the timing between the two earns 34 and 44.

. In. Figures '7, 4, 8 and 3, two forms of cutters are illustrated, theone shown in .Figuresa and 3 beingdesigned for use in fabricating so-called longworkpieces, and that shown in Figures 7 and 4 being designed for use in fabricating socalled short workpieces. These cutters are preferably constructed with a body portion, through which are openings to receive the fastening screws and a head portion 60 of greater thickness thanthe body portion, in the end face of which is the recess 6! to receive the wire, and to retain and carry it-from-one station to the other. For a workpiece longer than the :thickness of the head portiontfl, the feed stop 55 is outside of the cutter, as in Figure 6. For a workpiece shorter than the thickness of the; head portion 60 a feed stop 62 is used, having a relatively narrow tip 64. For such short length workpieces each cutter I6 is provided with a slot 63 of the desired depth, and into which projects the tip 64 of the feed stop that is in the path of the wire as it is fed through the cut-off die 56 into the opening 51 between the cutters when in register with the wire line. The thickness of the head portion 60 of these cutters is such that they give great stability to the projecting portion of the wire therebetween as the same is cut off from the wire length. This is one favorable factor in insuring a rigid holding of the wire during the cut-off operation, an ,essentialin producing a square end workpiece. This relative thickness of the cutter head is possible in this invention because the workpiece is not presented to the fabricating die by the cut-off knives or cut-;

ters, as heretofore. In practice, it has been found that heretofore these cutters must be materially reduced in thickness to prevent interference with the advancing punch at the fabricating die.

Herein the heads 60 of the cutters are relatively,

thick regardless of the length of the workpiece and rigidly support the workpiece and hold it against distortion while being severed.

On the rock shaft 26 is a rock arm 65, to which is secured a finger block 66, carrying a finger On this finger arm is a latch 68 held arm fi'i. by a bolt 69 under the tension of a spring Hi. In the end of the arm 61 is a notch 1!, open at one side, and over which projects an end of the latch 68, thus forming a notch H for the recep tion of a workpiece. Thefinger block 66 is adjustable on the rock arm 65 and the finger arm 67 on the finger block 66, and whereby the notch ll may be moved into alignment with the center of the fabricating die I 2, and thus bring the work- On the side shaft is a cam hub 80, to which is secured the cam 8| by the screws 82, and a cam segment 83 adjustably securedthereto by the same screws 82.

Journaled on the pin 84, fixed in the frame H3, or other rigid part, is a rock arm 88, carrying a cam roll 85, which rides against the face of the cam 8| and cam segment 83, being held in such contact by a rod 89 connected by a pintle 99 with the rock arm 38 and slidable within a nut 86 in the bracket 81 secured to a fixed part and a spring surrounding the rod.

Between the rock arms 88 and 9| on the shaft 14, is an adjustable connection, comprising a rod 92, secured by a yoke 9! pivotally connected with the rock arm 9i and by a yoke 93 to the rock arm 88. Between the yoke 93 and a collar 94 on the rod 92 is a spring 95, which will yield when the lug I9 is in contact with the stop screw 18 when the apparatus is set for short workpieces. The timing of the transfer is such that the finger arm 6] is quickly withdrawn from itsposition in front of the fabricating die I2 and earlier or later to clear the advancing punch so that very short length blanks may be accommodated; For cut-a;

ting off workpieces that are longer than the thickness of the cutters, the notch H is carried above the push-out station. When in such a position it dwells while the workpiece between the cutters is carried over from the cut-off station in front of the push-out pin 54. The finger arm 61 now moves down and snaps onto the workpiece which rests in the notch H under slight pressure from the latch 68. After the blank has been pushed entirely out of the cutters and into the notch H, the pusher pin 54 is withdrawn quickly and the arm arm 65 swings to the left, as shown in Figure 11, causing the finger arm 61 to swing downwardly carrying the workpiece in the notch'll into register with the fabricating die l2, at which time the lug 19 contacts the stop screw 11 and is adjustable for position as thespr ing 98, surrounding the rod 89 will yield'for such adjustment.

The cam BI and cam segment 83 are utilized for transferring both short and long workpieces. When transferring a workpiece shorter in length than the thickness of the cutters, the finger arm 61, with the notch in its outer end, stops-at the push-out station, and then the spring 95 is compressed to allow the full stroke of the cam BI and cam segment 83.

When cutting off workpieces longer than the thickness of the cutters, the stop screw 18 is not utilized and the full stroke of the cam,8l and cam segment 83 is used as above described. The cam segment 83 is adjustable on the cam 81 through the screws 82 and slot' 96, to give an adjustment of timing to the rock arm 65, so that the finger arm 61 can be returned from the fabricating die l2 earlier or later as may be required.

In Figure 4 the feed stop 62 is positioned closer to the die block than is the feed stop shown in Figure 3. I

With the mechanism herein disclosed a workpiece is cut from a wire length witha severed face that is at a right angle to its length. Such right angle or square face is advantageous in future operations upon the workpiece. The end of the wire in the cut-off die also has a perfectly square face and becomes one end of the next succeeding workpiece cut therefrom, thus both ends of th workpiece are at right angles to the length of the workpiece and parallel with each other. In order to withstand the cut-off strain the parts upon which this duty comes mustbe relatively heavy and substantial to properly perform their functions. The workpiece when out off, however, is relatively light. Therefore, the mechanism that transfers the workpiece from the cutoil' mechanism to the fabricating dies is also relatively light. This differential in bulk, strength, etc., in favor of the transfer mechanism, is apparent in this invention. The cutters, plunger and associated parts are relatively heavy and strong in comparison with the finger arm '61, finger block 66 and rock arm 65, forming part of the transfer mechanism. In headers of this general character, heretofore made, the cut-off mechanism and the transfer mechanism are one and the same, and therefore, do not have a differential as to weight, strength, etc. Again, in such headers, the cut-off and transfer mechanism dwell a sufficient length of time in front of the fabricating dies to permit the workpiece to be removed therefrom and presented to the die before a simceeding feed of wire can take place. In the construction herein disclosed, however, immediately the transfer mechanism receives the workpiece the cut-off mechanismreturns to the wire line anism carries the workpiece intoline with the fabricating die. Thus thetiming is easier and an increased speed of operation and output is achieved. In this mechanism the transfer arm is positively actuated through a link connected with the rock arm at a point distant from the axis of rotation of the rock arm, thus inducing ease and simplicity of action as distinguished from the conventional type of transfer mechanism, wherein the rock arm is fixed on a rock shaft and actuated thereby.

With this improved mechanism, the header is operated at an increased speed with resulting increased output. While operating under this increased speed, if perchance a workpiece when ejected from the fabricating die does not drop by gravity suificiently fast to be out of the path of another punch, the transfer mechanism, carrying the new workpiece will engage it and assist in driving the workpiece downward. When the punches are horizontally shifted, the second punch at one side of the first punch is in a horizontal line and the workpiece only clears a single punch as it drops by gravity or is forced downwardly by the transfer mechanism. This differs in operation from the conventional type of header. where the two punches are in a vertical line and the workpiece ejected from the fabricating die must clear in its downward travel the second punch located below. Consequently, so far as clearing the fabricated workpiec is concerned, the header, by reason of this improved mechanism is virtually a single stroke machine, due to the second punch being at one side of the first punch and in substantially the same horizontal plane.

This invention may be embodied in forms other than that shown herein and be within the scope and spirit of the accompanying claims.
